DESIGN AND FABRICATION OF AUTOMATED PNEUMATIC SHEARING MACHINE TO CUT ALUMINIUM SHEET

Automation within the contemporary world is inevitable. Any automatic machine focuses towards the economical use of man, machine and material well worth the most. For small and tiny scale industrial units the sheet cutting machine is manually operated. In this paper, solenoid valve and Arduino controller is used for automation. The machine works with the help of double acting pneumatic cylinder. The piston is connected to the moving cutter. The machine is easy to transport and transfer. The compressed air from the compressor is used as the force medium for this operation. There are double acting pneumatic cylinders, solenoid valves, flow control valves and the Arduino is used. The arm from the compressor enters to the solenoid valve. The function of solenoid valves all of air correct time interval. The 5/2 solenoid valve is used. At one position the piston is pushed by the air entering the cylinder thus obtaining cutting stroke. The releasing stroke is obtained by the movement of piston in backward direction due to the air entering the cylinder from the other side. The speed of the cutting and releasing stroke is varied by the Arduino controller.
